* feat(themes): added new theme
* fix(themes): screenshot updated
* fix(themes): image sizing
* chore(themes): updated theme description
* style(themes/developer): fix the indentation
* refactor(themes/developer): prefix "_omb_theme_developer_" to internal functions
* refactor(themes/developer): delimit returned values with newlines
"grep -P" is not POSIX. Instead of using PCRE to extract the results
separated by "---", we can simply separate the results with newlines
and use standard utilities (which assumes line-oriented data) to
manipulate the data.
* refactor(themes/developer): use "_omb_util_command_exists"
* refactor(themes/developer): use awk to pick the activated conda env
* fix(themes/developer): remove meaningless forks
* fix(themes/developer): use "_omb_util_put" instead of "printf"
* style(themes/developer): fix coding styles
* chore(themes/developer): clean up codes for debugging
* fix(themes/developer): fix wronge uses of arithmetic commands
* fix(themes/developer): localize variables used in functions
* refactor(themes/developer): use "return_delimited" at the end of functions
* fix(themes/developer): fix a problem that it sometimes fails to extract CPU usage
* fix(themes/developer): avoid mixing stdout
This attempted to run the commands to extract information in parallel,
but this may result in interleaved information in some operating
system (depending on the way how the C library performs buffering and
how the syscall write(2) issued by multiple processes would interfere
with one another).
There are other parts we can optimize, so we would compensate the
overhead with the optimization of other parts.
* perf(themes/developer): load prompt information through REPLY
* perf(themes/developer): reduce the number of forks
* fix(themes/developer): suppress error message of non-existent commands
* fix(themes/developer): disable prompt element with unavailable information
